Export single CATIA body from CATPart as stl using VBA macro - vba

Question

Is it possible to export a single CATIA body as STL without creating a separate part with it?
For the time being, I have coded a script which loops through the CATParts present in a folder, fetches the contained bodies and create a single CATPart with each of them and export into stl format.
Dim output_stl_path_HD As String
Dim output_stl_path_MD As String
Dim output_stl_path_SD As String
Dim output_stl_path_via_points As String
Dim output_transformations_path As String
Dim input_path As String
Sub CATMain()
'Path for output file
input_path = CATIA.ActiveDocument.path + "\"
Dim it As Integer
Dim prod As Product
Dim t_p_ref(11)
'List of part names to export
Dim list As Collection
Set list = New Collection
'GET LIST OF CATPART IN FOLDER
Dim objFSO As Object
Dim objFolder As Object
Dim objFile As Object
Dim i As Integer
'Create an instance of the FileSystemObject
Set objFSO = CreateObject("Scripting.FileSystemObject")
'Get the folder object
Set objFolder = objFSO.GetFolder(input_path)
i = 1
'loops through each file in the directory and prints their names and path
For Each objFile In objFolder.Files
'print file name
If (InStr(objFile.path, ".CATPart")) Then
list.Add (objFile.name)
' Set objDocument = CATIA.Documents.Open(objFile.path)
Dim srcDoc As PartDocument
Set srcDoc = CATIA.Documents.Open(objFile.path)
Dim srcPart As Part
Set srcPart = srcDoc.Part
Dim oSel As Selection
Dim bodies1 As Bodies
Dim body1 As body
'
Set bodies1 = srcPart.Bodies
For Each single_body In srcPart.Bodies
A = exportStl(single_body)
Next
Set body1 = srcPart.Bodies.Item(i)
'Dim BoxProduct
'BoxProduct = MsgBox("Quantity of the bodies found:" & srcDoc.Part.Bodies.Count & "", 64)
End If
Next
End Sub
Public Function exportStl(ByVal myBody As body)
Dim oSrc As Part
Dim oTgt As Part
Dim oSrcDoc As PartDocument
Dim oTgtDoc As PartDocument
Dim oBod As body
Dim oSel As Selection
'Sets documents for Source and Target files
Set oSrcDoc = CATIA.ActiveDocument
Set oTgtDoc = CATIA.Documents.Add("Part")
oTgtDoc.Product.PartNumber = myBody.name
'Gets Body to copy
Set oSrc = oSrcDoc.Part
Set oTgt = oTgtDoc.Part
Set oBod = myBody
Set oSel = oSrcDoc.Selection
'Copies Body
oSel.Add oBod
oSel.Copy
Set oSel = oTgtDoc.Selection
'Sets and Pastes in Target file as result with link
oSel.Clear
oSel.Add oTgt.Bodies.Item(1)
oSel.Paste
oSrcDoc.Selection.Clear
CATIA.ActiveDocument.ExportData input_path + myBody.name, "stl"
CATIA.ActiveDocument.Close
End Function

Catia V5 is capable of creating STL files from parts (CatiaPART files), but not from assemblies (CatiaPRODUCT files) or geometrical representations (car files). Therefore, source files, including those saved in a neutral format (STEP or IGES, for example), must be saved as parts. If the source design was saved as an assembly, it is imported to Catia as a product. -

I tried exporting CATBody but was unsuccessful. We must have a CATPart to generate STL
